Trico Marine Services is building two of the well-proven GPA 640 class DP2 equipped platform supply vessels at Bender Shipyards in Mobile Alabama.
As with others of these Guido Perla and Associates designed vessels, main propulsion will be diesel electric. Each boat will employ three diesel-powered generators including two 1,825 kW (2,447 hp) generators powered by 16-cylinder Cummins QSK60 D(M) engines and one 910 kW (1,220 hp) generator powered by a Cummins KTA38 D(M) engine. This engine configuration has demonstrated excellent flexibility and fuel savings as one or more of the generators can be shut down for stand-by or slower moving operations such as seismic or cable laying that are often required of this type of vessel.
The first of the 210 x 54 x 19-ft. vessels is anticipated for a March 2008 delivery with the second to follow in July 2008.
